ARCO 3-Wire Rectifier for OMC Outboards
A direct-replacement 3-wire rectifier for OMC outboard engines. The rectifier converts AC current from the stator into DC current to charge the battery and power onboard electronics. When the original unit fails, the battery stops charging underway — this ARCO replacement restores the charging system to full function using a 3-wire connection that matches the factory wiring harness.

Pairs Well With
Parts Desk Insights
Best suited for OMC outboard owners experiencing a battery that won’t hold a charge underway, or a charging system that shows no output voltage at the battery terminals with the engine running. Before replacing the rectifier, confirm the stator is producing AC voltage — a failed stator will produce the same symptom. Cross-reference your existing OMC part number against the compatibility list above to confirm fitment before ordering.
